To all whom it may concern:

Be it known that 1, JOHN SHEEHAN, engineer, a citizen of the Commonwealth of Australia, and resident of Melbourne, State of Victoria, Commonwealth of Australia, (whose postal address is 32 Crossley street, Melbourne, in the State of Victoria, Commonwealth of Australia,) have invented cer- 1: places. Hitherto with soda fountains and such like apparatus for drawing ofi aerated waters, the syrup or flavoring essence is first of all poured or tapped into the glass and the soda water from the carbonator vessel (in which the water is charged with compressed car-' bonic acid gas) is then directed into the said glass by means of a tap or valve.

The object of this invention is to provide means whereby the syrup and the soda water are discharged into the glass at the same time by the one operation of a valve or tap, producing thereby soda water or o her like beverage of a better quality than hitherto, and in a more expeditious and economical manner. I accomplish this I means of a special arrangement of a combined -mixing and discharge tap or valve which is connected to a carbonator on the one hand (containing water charged with carbonic acid gas under pressure) and to a vessel containing syrup on the other hand also under pressure or at a sutiicient height in such manner that by one operation of a handle or lever of the tap a quantity of syrup and a quantity of soda water is discharged into a glass or other receptacle. This tap may be so designed that optionally two distinct syrup valves may be operated whereby the same tap may be utilized for drawing off two distinct beverages.

This invention comprises broadly a syrup vessel under pressure (or at a sutlicient height to provide a head) a carbonating vessel under pressure, and the combined mixing and discharging tap or valve connected to the two. Th s mixing tap or valve comprises one or more inlets for the syrup having controlling valves, an inlet for the soda water having a controlling valve. a chamber to contain a certain quantity of soda Water, a

obiect by shifting valve for reducing the pressure of gas in the said chamber, means for causing the flow of soda water into the glass from the chamber at the same time as the flow of the syrup thereto;

The invention will now be more fully vde scribed aided bya reference to the accompanying sheets of drawings in which Figures 1 and 2 show the general arrangement of the invention, Fig. 1 being where the syrup is forced upward by gas pressure and Fig. 2 where the syrup vessel is arranged at a sufficient height to provide pressure by gravity. Fig. 3 is an elevation of the syrup vessel. Fig. 4 a detail sectional view of the mountings on the neck of the syrup vessel. Fig. 5 is a detail secti n showing the means devised for attaching the gage or sight glass to the said vessel. Fig. 6 is a side elevation of a tap designed to draw off only one kind of beverage, the syrup valve being shown in section. Fig. 7 is a central vertical section of the tap illustrated in Fig. 6 showing the soda water controlling valve; and the valve arrangement for discharging the soda water into the glass. Figs. 8 and 9 are detail viewsof the soda water controlling valve. Fig. 10 is a vertical section of the snifting valve. Figs. 11 and 12 show a modified form of tap for drawing oli'alternatively two separate beverages. Fig. 13 is 'a sectional view of a modified form of valve to control the soda water.

Referring to these drawings A is the tan.

or valve attached to a bar counter. B the syrup vessel. C the carbonator and I) the carbonic acid cylinder. In Fig. 1 the syrup vessel B, carbonator C and gas cylinder D, are shown as arranged in the cellar. the discharge of the soda water and the syrup being effected by the pressure of gas. In Fig.

2 the carbonator C and the gas cylinder l) are shown in a position adiacent to the counter while the syrup vessel B is arranged at a suflicient height to supply the syrup by gravity. The tap A is connected to the struction aremounted on the said cylinder D to regulate the pressure of gas to the respective vessels B and C.

The syrup vessel B (Figs. 3, 4 and 5) is preferably an eartlwnwa-re jar having a gage or sight glass B mounted on its side for showing the quantity of syrup left therein. This sight glass B is mounted in sockets B" or the like which are held in position by tubular bolts B (see Fig. 5) the heads of which are adapted to bear against the in-v side of the jar or vessel B while a nut B on the end of the said tubular bolt B enables the socket pieceB to be forced tight against the side of the vessel as shown with suitable packing to make a liquidtight joint. The tubular bolt B is placed in position by being passed through the neck of the jar which is large enough to accommodate the head of the bolt when the bolt proper can be drawn through the wall of the jar B by any convenient means.

The neck of the jar or vessel B is furnished with a cap or head B which comprises a gas inlet valve B connected to the pipe B leading to the carbonic acid gas cylinder D, a syrup outlet valve 13 connected to the pipe B leading to the tap A and an ordinary safety valve B for allowing any excess of gas pressure to escape from the said vessel or jar B. The said head or cap B is also fitted with a feeding orifice having a removable plug B for filling purposes. The syrup outlet to the valve B is connected to a pipe or tube B which leads to within a short distance of the bottom of the jar or vessel B in order that the syrup may be forced up to the tap A by the pressure of 'as.

b The carbonatoVC is of ordinary construction mounted on a suitable frame having a mixing'or agitating device operated by a handle C" and is fitted with a gage or sight glass C! and is connected to the tap A by the aforesaid pipe C through which the soda water is forced. If desired the soda water pipe C leading from the carbonator to the tap A may be connected to a cylinder C arranged in an ice box 0 situated under the counter or the like for the purpose of cooling the liquid before delivery. The said carbonator C is also connected to the reducing valve Con the gas cylinder D by. the pipe 0 as before stated and shown in Fig. 1.

The mixing tap or valve A may be constructed either as shown in Figs. 6, 7, 8, 9 and 10 which is designed for drawing off only one kind of beverage or it may be constructed as shown in Figs. 11 and 12 which is designed for drawing ofi' alternately different beverages, and is therefore adapted to operate two distinct syrup valves. This 1 tap comprises one or more syrup inlets which are connected to the syrup vessel B by the pipe B and furnishedv with one or more syrup valves A a soda water inlet A lead ing to the soda water valve A and a port or passage A leading to a soda water chamber A adapted to contain a certain quantity of soda water.

The tap illustrated in Figs. 6 and 10 is designed for drawing off only one kind of beverage'and is fitted with a rotary soda 'water controlling valve adapted to be operated by a horizontal lever A In Fig. 13 a modified form of such valve is shown which comport A both of which are in communication with the carbo-nator C by the pipe C, thereby enabling soda water to be forced from the carbonator C to the soda water chamber A. In the bottom of the said chamber A" is a spring actuated valve A which is adapted to be closed by the pressure of soda Water thereon entering the chamber A through the port or passage A and the tube A connected thereto and is, opened when the pressure is released by the coiled spring A which is mounted in the nipple A in the bottom of the chamber A. This valve A -is tubular, and furnished with horizontal ports or perforations A through which the soda. water from the chamber A" is discharged into the glass. This valve A as before stated is closed by the pressure of soda water causing the spring A to be compressed and the ports A to be covered by the nipple A thus enabling the chamber A to be filled with soda water. When the pressure on the valve is released it is raised by the spring A to the position as shown in Fig. 7 and at the same time allows the soda water to be discharged from the chamber A through the perforations or ports A and How into the glass or the like at the same time asthe syrup. This soda water valve A as before stated is operated by the horizontal hand lever A (Fig. 6) in such manner that when the same is open the valve A in the bottom of the chamber A is closed preventing the flow of soda water through the glass, and the chamber A." is in open communication with the carbonator C and is filled with soda water. In conjunction with this soda water inlet valve A is a snifting or pressure reducing valve A which is adapted to reduce the pressure of gas in the soda water in the chamber A when the flow thereto is shut off from the carbonator. This valve A is constructed as shown in Fig. 10 and ada ted to be opened by a tappet arm A on t e horizontal handle A and closed by the coil spring A". The pressure of gas in the chamber A is discharged through the passage a and the pipe a to atmosphere or to the ice chamber.

The syrup valve A is arranged upon the side of the soda water chamber A and constructed as shownin Fig. 6. The valve is held up against the seat in the casing by means of a coil spring in order to .govern the flow of syrup to the glass through the port or passage b and the tube 1). To regulate the quantity a screwed spindle valve B is provided to regulate the size of the syrup passage connecting the chamber of the valve A with the pipe or tube B leading to the syrup vessel or jar B. I

The tappet arm A on the lever A which operates the syrup valve A and snift valve A is furnished with two contacting faces A and A -the face A adapted to operate thc snifting valve A and the face A adapted to operate the syrup valve A. The said tappet arm A is so designed that by the handle A being operated a given distance only the soda water valve A and the snifting valve A are operated, thereby allowing only soda water to flow into the glass, but by moving the said handle to the end of its stroke the syrup valve A is operated and syrup is allowed to flow into the glass with the soda water.

The modified form of soda water valve shown in Fig. 13 which is preferably used when two syrup valves A are employed comprises a perforated valve A having a transverse opening A therethrough. A perpendicularly disposed circular opening A is also provided therein crossing the said opening A and in which a reciprocating spindle A is loosely mounted, on the lower end of which ismounted a closure member A for the said valve A the said closure member A being kept in contact with the valve A by a coiled spring A mounted within the chamber A That portion of the spindle A 9 passing through the valve A is made of flat or triangular shape in cross section as at A thereby forming passages about the same which when the said spindle A is depressed or forced down opening the valve by downward movement of the closure member the soda water passes through the valve into the chamber A and thence into the soda water chamber A? through the passage A and pipe or tube A. This type of valve is operated by the vertically arranged handle A shown in Figs. 11 and 12 having a cam shaped projection A which when the handle is in a vertical position as shown in Fig. 11 theprojection A contacts with the spindle and forces the same down and opens the valve.

of syrup being delivered I the carbonator valve,

The syrup valves A are operated by cams E and E mounted on the said handle A while the snifting valve A is operated by a cam face or recess E formed in the side a or inner face of the cam E. Thus by operating the handle A in a forward direction as indicated by the arrow one syrup and soda water is discharged into the glass, while by operating the handle A in a backward direction another syrup and soda water is discharged, giving two separate beverages as indicated by the outer dotted lines in Fig. 11. When the handle is in. a verticalpcsition shown in Fig. 11 the soda water chamber A is in communication with the carlonator C and is filled with soda water, then by moving the handle forward to a position indicated by the inner forward dotted line the soda water valve A is released and the snifting valve A is operated by the cam face or recess E without the faces E and E contacting with the cam syrup valves, thus soda water only may be discharged.
